the multy choices in the yellow is about theory of machines i want the solution in about 45 m please

14 1 121 1 10 The unbalance problem in rotating parts show clearly: 2 points In the high speed When the speed equals to zero In the low speed In the moderate speed In the belt drive rules, if the times of wrapped belt around a post increases, the force ratio 2 points does not affect increases remains constant decreases The system of belt drive in pulleys depended on 2 points power tension friction velocity the principle of times of wrapped belt around post ap angle) has application in 2 points winches motorcycle belt drive of car door mechanism The faction of a govem is to regulate the mean speed of an engine, when there 2 points changes in load changes in fuel type fluctuations in power Variations in toru The controlling force is provided to the action of gravity as in movemer or by a pring in case of semo 2 points Watt.

Answer 1

#0 is The unbalance problem in rotating parts high speed, observed at Explanation : - Transverse Vibration id dominant at high speed. 2 In the belt drive rules, if the times of wrapped belt around post increases, the force ratio. does not affect. Explanation : we know, (1/2) = e. Since the Contact angle and coefficient of friction is not changing, so ratio of force will not change 3 The system of belt drive in pulleys, depend on Tension. Explanation :- (T-T2) *V = Power The principle of times of wrapped belt around post (lap angle) has application in belt drive of Car. Explanation : where, lap angle

The function of a governor is to regulate the mean speed of an engine, when there changes in load are Explanation :- If load increases, its speed decreases, therefore it becomes necessary to increase the supply of working fluid so, Governor keep the Constant. mean speed 6. The controlling force is provided either by the action of gravity as in by spring as in case of. Hartnell Governor Watt Governor or 7. The proell governor depends on Centrifugal Centrifugal force

All answers are underlined and explanation are given. Thank You and stay safe.
